The KAD/ENC/005 is used to encode data from any KAM-500 module in an IRIG-106 Ch.4 PCM stream. Frame configuration is versatile and fully IRIG-106 compliant. Parameters to be transmitted are stored in predefined locations in RAM. Each parameter has a word definition that includes the location in RAM, bits per word, MSB sent first/last and parity. This definition controls the RAM reader and the parallel-to-serial converter.
The KAD/ENC/005 has differential-ended (D/E RS-422) outputs for data and clock along with buffered TTL outputs for NRZ-L and the four-bit/word/minor-frame/major-frame pulses. Multiple KAD/ENC/005 modules can be included in a KAM-500 system and parameters can be sent to some or all of the encoders. For example, a system can have two encoders using different codes, data rates, word lengths, and frame lengths. The only restriction is that an integral number of major frames be transmitted per acquisition cycle.
